Mostly they are the same, but some have a few more details and clarifications in the selectors specification. Selectors also defines additional pseudo classes not mentioned in css3-ui.

During TPAC, a task was assigned to Bert (http://www.w3.org/Style/CSS/Tracker/actions/656) to ask Steven Pemberton and try find if there are any implementations. Steven suggested XSLTForms as the most likely candidate, but it does not implement these pseudos. Bert found one implementation: X-Smile (http://www.xsmiles.org/), but this is unmaintained since 2008.

Since we resolved on removing both of these (http://www.w3.org/mid/CADhPm3tfM7ewisaP+WGjjWa_TU35_JFQmdaaobsECytTEJR7hA@mail.gmail.com), here is a patch to do it.
